Distribution Manifold

FIG. 5 illustrates distribution manifold 330 in further detail. In someimplementations of the invention, distribution manifold 330 is formedseparate from and then coupled to tubing 310. In some implementations ofthe invention, distribution manifold 330 is formed as part of tubing310. According to various implementations of the invention, distributionmanifold 330 dispenses fluid from an interior of distribution manifold330 to an exterior of distribution manifold 330 via a plurality ofdistribution holes, such as distribution holes 510 in FIG. 5. In someimplementations of the invention, distribution holes 510 are formedaround a circumference of distribution manifold 330. In someimplementations of the invention, distribution holes 510 are formedalong a length of distribution manifold 330. In some implementations ofthe invention, distribution holes 510 are formed along the circumferenceand the length of distribution manifold 330. In some implementations ofthe invention, distribution holes 510 are formed only along a portion ofthe circumference and/or a portion of the length of distributionmanifold 330. In some implementations of the invention, a singledistribution hole 510 may be used. In some implementations of theinvention, a plurality of distribution holes 510 may be used. Variousnumbers of distribution holes 510 may be used and configured in variouspatterns as would be appreciated. In some implementations of theinvention, distribution manifold 330 may be terminated (i.e., closedsuch that no fluid may exit its end). In some implementations of theinvention, distribution manifold 330 may be terminated by a tubing cap520.

In some implementations of the invention, distribution holes 510 aresized based on various fluid parameters of the sanitizing fluid, forexample, viscosity, evaporation rate, density, and/or other variousfluid parameters. In some implementations of the invention, distributionholes 510 may be “self-healing” in the sense that when the sanitizingfluid in distribution manifold 330 is under pressure (e.g., pressurecreated by fluid pump 140), distribution holes 510 open, allowingsanitizing fluid to be dispensed; and when the sanitizing fluid indistribution manifold 330 is not under pressure, distribution holes 510close, allowing little, if any, sanitizing fluid to be dispensed. Suchself-healing implementations may be configured using, for example, nylontubing, or the like, as would be appreciated. In some implementations ofthe invention, distribution manifold 330 is coupled to and/or disposedwithin door handle grip 120.

In some implementations of the invention, fluid container assembly 300is a replacement fluid container assembly 300 such that once the fluidis emptied from fluid container assembly 300, such an “empty” fluidcontainer assembly 300 may be removed from door handle 100, and a newfluid container assembly 300 may be installed in door handle 100. Insome implementations of the invention, fluid container assembly 300 maybe sold together with door handle 100; while in some implementations ofthe invention, fluid container assembly 300 may be sold separately fromdoor handle 100 as would be appreciated. In some implementations of theinvention, fluid container 130 may be refillable without replacing fluidcontainer assembly 300.

Door Handle Grip

FIG. 4 illustrates door handle grip 120 in further detail. Door handlegrip includes a distal grip end 410 and a proximal grip end 420. In someimplementations of the invention, grip wall 125 forms a hollow interiorgrip chamber 440 extending from proximal grip end 420 to distal grip end410. In some implementations of the invention, distal grip end 410 isclosed and proximal grip end 420 is open. In some implementations of theinvention, both ends 410, 420 are open. While door handle grip 120 isillustrated as generally cylindrical in FIG. 4, other shapes andconfigurations may be used. For example, door handle grip 120 may beconfigured to conform with any shape of a door interface with which theuser comes into contact to operate door handle 100, including configuredto conform entirely around such door interface, partially around suchdoor interface, or simply on one or more surfaces of such doorinterface, as would be appreciated.

In some implementations of the invention, a plurality of grip holes(illustrated, for example, as a plurality of grip holes 430 in FIG. 4)are formed into grip wall 125. In some implementations of the invention,grip holes 430 serve to transfer the fluid from interior grip chamber440 to an exterior grip surface 450 of door handle grip 120. In thisway, the fluid entering interior grip chamber 440 from proximal grip end440 is dispensed through interior grip chamber 440, through grip holes430 and onto exterior grip surface 450. In some implementations of theinvention, grip holes 430 are located on door handle grip 120 in regionswhere the user is likely to engage door handle 100 in order to operatedoor handle 100. In some implementations of the invention, grip holes430 are formed around a circumference of door handle grip 120. In someimplementations of the invention, grip holes 430 are formed along alength of door handle grip 120. In some implementations of theinvention, grip holes 430 are formed along the circumference and thelength of door handle grip 120. In some implementations of theinvention, grip holes 430 are formed only along a portion of thecircumference and/or a portion of the length of door handle grip 120. Insome implementations of the invention, a single grip hole 430 may beused. In some implementations of the invention, a plurality of gripholes 430 may be used. In some implementations of the invention, gripholes 430 are formed in a length of about a hand's width (e.g., 3-6inches). In some implementations of the invention, grip holes 430 areformed in a length of about two hand's width (e.g., 6-12 inches). Otherlengths of grip holes 430 along door handle grip 120 may be used aswould be appreciated. Various numbers of grip holes 430 may be used andconfigured in various patterns as would be appreciated.

In some implementations of the invention, distribution manifold 330 isoperatively coupled to door handle grip 120. In some implementations ofthe invention, distribution manifold 330 is disposed in interior gripchamber 440 of door handle grip 120. In such implementations, when thefluid is dispensed through distribution manifold 330, the fluid entersinterior grip chamber 440 of door handle grip 120 and is subsequentlydispensed through grip holes 430 to exterior grip surface 450 of doorhandle grip 120. In some implementations of the invention, distributionholes 510 are aligned with grip holes 430 to facilitate flow of thefluid through distribution manifold 330 to exterior grip surface 450 ofdoor handle grip 120 as would be appreciated.

In some implementations of the invention, distribution manifold 330 isintegrated directly into door handle grip 120. In such implementations,tubing 310 is operatively coupled to door handle grip 120 which in turnfunctions as both grip and distribution manifold as discussed above.

Check Valve

In some implementations of the invention, check valve 340 is coupledbetween fluid pump 140 and distribution manifold 330. In someimplementations of the invention, check valve 340 is coupled directly tofluid pump 140. In some implementations of the invention, check valve340 is coupled directly to distribution manifold 330. In someimplementations of the invention, check valve 340 is coupled to tubing310 in between pump 140 and distribution manifold 330 (i.e., check valve340 coupled between tubing 310A and 310B as illustrated in FIG. 3).

According to various implementations of the invention, check valve 340is configured to allow the fluid from fluid container 130 to flow inonly one direction, namely from fluid container 130 to distributionmanifold 330. When actuated, fluid pump 140 pumps (i.e., forces) thefluid from fluid container 130 into tubing 310, through check valve 340and on toward distribution manifold 330. Once pressure from fluid pump140 subsides, check valve 340 closes to prevent the fluid from flowingback to fluid container 130 and also to maintain pressure in tubing 310between check valve 340 and distribution manifold 330 until the fluid isdispensed.

In some implementations of the invention, check valve 340 may be shapedor “keyed” to aid in aligning or positioning various components of fluidcontainer assembly 300 in door handle 100. For example, FIG. 6illustrates fluid pump 140 coupled to a keyed check valve 630 inaccordance with various implementations of the invention. In someimplementations of the invention, a pump seat 610 may be integrated intointerior housing chamber 112 to align, orient and/or position fluid pump140 in interior housing chamber 112. As illustrated, pump seat 610 mayinclude a keyed check valve receiver 620. In some implementations of theinvention, only keyed check valve 630 may fit into keyed check valvereceiver 620. FIG. 7 illustrates an example of a keyed hole 710 formedin keyed check valve receiver 620 configured to receive keyed checkvalve 630. As would be appreciated, keyed hole 710 and keyed check valve630 may have corresponding shapes different from that illustrated inFIG. 7. For example, while keyed hole 710 (and corresponding keyed checkvalve 630) is illustrated as generally hexagon and isometric in shape,keyed hole 710 may be other than generally hexagonal in shape or otherthan generally isometric in shape. Also for example, while keyed hole710 is illustrated as having two semicircular protrusions, keyed hole710 may have other numbers of protrusions or other indentations (e.g.,semicircular indentations) as would be appreciated. In someimplementations of the invention, keyed check valve 630 may be frictionfit into keyed hole 710 as would be appreciated. In some implementationsof the invention, keyed check valve 630 may be snap fit into keyed hole710 as would be appreciated.

In some implementations of the invention (not otherwise illustrated),keyed check valve 630 may be directly coupled to distribution manifold330. In such implementations, keyed check valve receiver 620 may beintegrated into door handle grip 120 to align, orient, and/or positiondistribution manifold 330 in door handle grip. In some implementationsof the invention (not otherwise illustrated), keyed check valve 630 andkeyed check valve receiver 630 may be disposed at various locations indoor handle 100 to maintain alignment, orientation, and/or position ofvarious components of fluid container assembly 300 as would beappreciated.

While keyed check valve 630 is described herein as a single component,it may be separated into two separate components, namely a check valveand a key, as would be appreciated. While fluid pump 140 and keyed checkvalve 630 are illustrated in FIG. 6 as being directly coupled to oneanother, in other implementations, tubing 310 may be disposed betweenfluid pump 140 and keyed check valve 630 as would be appreciated.

Tubing Cap

In some implementations of the invention, tubing cap 320 is shaped or“keyed” to a corresponding key hole in distal end 410 of interior gripchamber 440 of door handle grip 120. In some implementations of theinvention, tubing cap 320 is sized to friction fit or snap fit tubingcap 320 into the key hole of interior grip chamber 440 of door handlegrip 120 to maintain alignment, orientation, and/or position ofdistribution manifold 330 within interior grip chamber 440 as would beappreciated.

Fluid Container Housing External to Door Handle

In various implementations of the invention, fluid container 130 (andassociated components) are disposed externally to a door handle. FIG. 8illustrates a fluid container housing 820, including fluid container130, separate from and external to a door handle 830 in accordance withvarious implementations of the invention. Such implementations may bedesirable in situations where space, access, clearance and/orconfiguration considerations do not permit installation of door handle100. In these implementations of the invention, fluid container housing820 houses fluid container 130 and other components of fluid containerassembly 300 (not otherwise illustrated in FIG. 8) as would beappreciated. Fluid container 130 is operatively coupled to externaltubing 840, which in some implementations of the invention, may becovered, for example, with braided reinforcement to protect externaltubing 840 as would be appreciated. In some implementations of theinvention, fluid container housing is mounted on the same side of a door810 as door handle 830. In some implementations of the invention, fluidcontainer housing is mounted on the opposite side of door 810 as doorhandle 830. In some implementations of the invention, fluid containerhousing is mounted on a wall (not otherwise illustrated in FIG. 8) neardoor 810 on either the same or opposite side of door 810 as door handle830. Depending on which side of door 810 fluid container housing 820 ismounted in relation to door handle 830, external tubing 840 may beconfigured to pass through a hole 850 in door 810, such as isillustrated in FIG. 8. Then, in a manner similar to that describedabove, external tubing 840 is operatively coupled to door handle grip120 surrounding door handle 830. These implementations of the inventionmay utilize a battery-operated electrical pump disposed in or proximateto fluid container housing 820 and a switch disposed in door handle 830or in door handle grip 120 for purposes of dispending fluid from fluidcontainer 130 to exterior grip surface 450 of door handle grip 120.

While various implementations of the invention have been describedherein in reference to certain door handles illustrated in the drawings,for example, other door handles and configurations thereof may be usedas would be appreciated.
